通过对切割过程的观察和研究,本课题采用了机电一体化系统设计思想,对其
整体造型、机械结构和控制系统进行设计,此棒料切割机电一体化系统主要由四个部分组成:机械本体、电子控制单元、执行器和动力源。工作原理是电动机通过带传动带动切割片做高速旋转运动,电机与工作台之间采用铰支撑方式,升降气压缸可推动切割片进行上下移动带动刀片完成顺序切割动作。切割机采用PLC控制各个气压换向阀的电磁铁,实现棒料的自动下料和切割以及检测工作。随动工作台前进速度也可以通过夹紧机械手夹紧棒料使之与棒料速度同步。横向切割时的切割速度可以通过气压缸来调节。现场运行情况表明,此切割机具有动作快、运动平稳以及与计算机联机方便等优点,能够降低工人的劳动强度,实现自动控制,提高劳动生产率。
铸棒线割机在连续的铸造中工作,它是一种既能有效的提高生产率,又在价格和使用方面能被广大用户所接受的一种新型的自动控制切割机。由PLC控制的气动铸棒切割机,其中融合了气压自动控制、机器人技术和PLC控制技术。PLC控制各个气动换向阀的电磁铁,由气缸驱动机械手完成顺序切割过程,实现了机械设计、电器控制和气动控制的有效结合。这种切割机具有控制方便,性能稳定,结构简单,调节、维修方便,生产率高等优点,具有广泛的应用前景。

Abstract
Based on the research of the cutting process, this subject adopts mechanical and electrical integration of system design idea, the overall modeling, mechanical structure and control system design, bar stock cutting the mechanical and electrical integration system is mainly composed of four parts: the basic machine, electronic control unit, actuators, and power supply. Working principle is the motor drives the cutting piece of high-speed movement, motor and adopts the hinged support method between the workbench, a falling cylinder can be driven to move up and down push cutting disc blade cutting action completed order, each hydraulic cutting machine adopts PLC control reversing valve electromagnet, implement automatic cutting and blanking bar work and tests. And servo table speed can also be through the clamping manipulator clamping bar to that of the bar speed synchronization. Transverse cutting when the cutting speed can be adjust by hydraulic cylinder. Field operation shows that, the design of the cutting machine is fast, smooth movement, and convenient with computer on line, it can improve the labor intensity of workers, to achieve automatic control, improve labor productivity.
Casting rod wire cutting machine in continuous casting, it is a can effectively improveproductivity, but also in terms of price and use can be accepted by the majority of usersof a new automatic control cutting machine. PLC controlled pneumatic casting rodcutting machine, which combines automatic pressure control, robotics and PLC control technology. PLC control various pneumatic solenoid valve, cylinder driven by a robot to complete the sequence of the cutting process, to achieve an effective combination of mechanical design, electrical controls and pneumatic controls. This cutting machine haseasy to control, stable performance, simple structure, regulation, easy maintenance,high productivity advantages, has broad application prospects.
